The ticking sounds like power saving / parking. Can be controlled from Linux. The usb ports should be able to provide enough power but also the rpi3 should too.

2- 1/2/4 Ram whats the best option will be for emulation retropie ?

1 is actually enough. If you want to use the desktop env then get 4. I got the 2gb model.

3- Can it use the same Power Supply like the 3b+ ?

Needs a USB-C PSU. Get the official one as there is a hardware fault causing compatibility with some PSUs.

4- Any ides when retropie will do an update for the pi 4 ? heard something like 2020 ;) ?

Check the RetroPie ama on Reddit. There's no release date but maybe there will be an alpha image before Xmas. Maybe :-)

4.1- When we will have the update will i have to install all again from scratch ???????

You can backup ROMs and configs and copy them back. It's not a long process really.

It depends on your setup and how you want to do it.
-If you have a linux machine then you can just plug the sdcard into your computer and copy them over at USB 3.X speeds.
-If you keep your roms/settings on an external usb drive (this is how I do it), then you can just unplug the usb stick/hdd/ssd and plug them into another computer to copy/backup.
-If you are going over the network through something like WinSCP, then yes, that is painfully slow. Ethernet connections on both the pc and Pi make this a more tolerable experience.

You can also follow this guide:

https://retropie.org.uk/docs/Running-ROMs-from-a-USB-drive/

This is meant to set you up to run roms externally, but it will also copy your entire Retropie folder to the usb drive. Then just unplug it after it is done and plug it into a computer to copy over. Just make sure to preformat the drive to be readable by whatever OS you plan on reading it.

Hope this helps a little.
